ok so i know this is a map not a texture pack but this will help texture makers alot. this contains every block and im pretty sure every item here it is thx C:
Not to rain on your parade and crush your ideas but there already is a great map for displaying all blocks and it's more compact then just a straight line of blocks, It;s called Kab's Texture Pack Showcase.
oh really? ok cool thx i will be sure to download it
